0 mesh with a wire diameter of 1.5 mmφ to 0.15 mmφ, preferably 1.1 mmφ to 0.25 mmφ, and more preferably 1.
Those having a diameter of 02 mmφ to 0.304 mmφ are preferably used.
As the mesh size becomes larger than 30 mesh and the wire diameter becomes smaller as the wire diameter becomes smaller than 0.304 mmφ, the wire diameter becomes small, so it depends on the kind of combustible material (synthetic resin etc.). Generally, it tends to be oxidized by a flame and tends to lack durability, which is not preferable. As the material of the wire net body, austenitic stainless steel, high manganese steel stainless steel, and austenite-ferritic stainless steel are preferably used. This is because it has excellent heat resistance and resistance to residual stress. Although the number of the wire mesh may be one layer, it is preferable to stack two or more wire meshes because the secondary combustion efficiency can be increased and the mechanical strength of the furnace wall surface can be increased. In addition, when a plurality of sheets are stacked, the mesh may be increased as the number of stacked sheets increases, and when the number of layers is one or two,
It is preferably 12 mesh or more. By reducing the opening ratio of the mesh of the ventilation furnace wall, it is possible to enhance the secondary combustion effect and prevent ash from blowing out from the wire mesh body.

As the width becomes narrower than 6 mm, the welding strength, the sandwiching strength, etc. become insufficient, and the durability tends to decrease.
As the width becomes wider, it depends on the thickness of the steel sheet forming the frame and the size of the furnace wall, but the weight tends to increase and the transportability tends to be poor.

For isosceles triangles and quadrangular shapes, three or more ventilating furnace walls are provided with a connecting portion on each side wall portion and are connected to each other, and one ventilating furnace wall is made openable to be incinerated. It may be used as a charging port, or an opening may be formed in the wall of one ventilation furnace to serve as a charging port for the incineration product. It is desirable to form an opening / closing door at the charging port. This is to prevent blowing up of sparks. The furnace body is formed in an incinerator having a substantially pyramid shape or an upper pyramid shape and a lower part having a box shape. The entire furnace wall may be an aeration furnace wall, but a part of the furnace wall may be replaced with a metal plate, a ceramic plate, a ceramic-coated metal plate, or the like. Furthermore, a part or part of the ventilation furnace wall may be replaced with a metal plate or the like to form a reflection part for incineration heat. By providing the reflecting portion on a part of the ventilation furnace wall, the combustion efficiency of the incinerated material can be increased by the reflected heat of the radiant heat and the incinerated heat. The reflective portion is formed with 40% or less of the area of the furnace wall, preferably 20% or less. This is to ensure breathability. In addition, the surface strength of the ventilation furnace wall can be reinforced by providing a reflecting portion or the like.

ながら燃焼効率を上げることができる。With this construction, at least the entire or part of the surrounding furnace wall is formed by the aerated furnace wall, so that the air permeability is remarkably excellent, the combustion speed is extremely high, and the incineration workability can be improved. Since the combustibility is extremely high, the amount of smoke generated can be suppressed. Further, since the wire mesh body and the perforated plate of the ventilation furnace wall are red-hot due to a strong flame, it is possible to secondarily burn smoke and incompletely combusted gas, and substantially completely oxidize and decompose it to eliminate smoke. Further, since the mesh and the hole diameter of the ventilation furnace wall are small, it is possible to prevent the ash from being blown to the outside, which is excellent in fire prevention and can prevent the work environment from being contaminated. Since the flame loses heat when passing through the wire mesh of the ventilation furnace wall, it prevents the flame from blowing out from the ventilation furnace wall, and since it falls below the ignition temperature of the outside air flow like the safety light of Wolf, it is a transitional fire. Etc. can be prevented and the safety can be remarkably enhanced. Since the furnace wall is connected at the connecting part so that the surroundings can be detached or folded,
It is possible to freely disassemble / assemble or fold / assemble by removing the connecting part or bending at the connecting part. When a furnace wall made of a metal plate or the like is partially used or a reflecting portion is provided, combustion efficiency can be improved while maintaining air permeability by the radiant heat or reflected heat.

Is closed, the input port lid part 7 is opened, and fired paper waste is input into the incinerator 1 through the input port part 6. Ventilation furnace wall 4 around the entire circumference of the furnace body
Since it is made of wire mesh, air enters from the entire circumference and it has excellent breathability, and the flame spreads all over the incineration at a stretch, and the air is further sucked from each ventilation furnace wall 4 by the upward flow due to the burning flame, so the combustion Since the inside of the furnace has a high temperature and the ventilation furnace walls 4a, 4b, ... Are made of metal, it reflects heat and absorbs the heat of the flame to generate radiant heat, which further increases the temperature inside the furnace, resulting in moisture. It is possible to incinerate kitchen garbage, which is often used. In addition, since the shape of the furnace body is a quadrangular pyramid, air is sufficiently supplied and the draft effect is high, so even if a tray made of synthetic resin is burned, complete combustion will occur and thin smoke will be recognized in the furnace, but this thin Smoke also ventilated furnace walls 4a, 4b ...
Is heated to a high temperature, it is possible to be secondarily combusted when passing through the wire netting of the ventilation furnace wall, and almost smokeless. The flame at the time of incineration is deprived of heat when passing through the wire mesh on the ventilation furnace wall, and is cooled to a temperature below the ignition temperature of the outside airflow like a safety light of Wolf. Therefore, the ventilation furnace wall does not blow out a flame to the outside and can prevent the transfer fire. Since the mesh of the wire mesh on the ventilation furnace wall is small, it is possible to prevent the leakage of sparks. After the incineration, the ventilation furnace wall is made of wire mesh and has a high thermal conductivity, so that it is cooled in a short time, and even if the ventilation furnace wall 4a on the front side is opened, there is no risk of burns. Drop the ash into the ash container 11. Next, the connecting portions 5a and 5b are removed, and the connecting portion 5c is folded as shown in FIG. 4 and stored in a warehouse or the like. Although the folding type is described in the present embodiment, it may be a disassembling type.
In this case, the connecting portion 5c can be easily achieved by using a detachable hanging metal fitting.

Since the front inclined furnace wall 52 is rotatably or detachably locked, a large amount of incinerator can be introduced by simply removing the front inclined furnace wall 52 to incinerate the incineration work. It can be significantly improved. Since the chimney portion is formed of a narrow gap, it is possible to prevent the emission of sparks and the like and to secondarily burn the smoke component and the volatile component.

向上させることができる。(Embodiment 5) FIG. 11 is a perspective view of a main part of an incinerator of a fifth embodiment having a chimney separately, and FIG. 12 is a development view thereof. The incinerator 70 of the fifth embodiment differs from the incinerator of the fourth embodiment shown in FIGS. 9 and 10 in that a top plate portion 71 made of a metal plate is rotated on the rear side wall 60 via a rotating portion 72. The top plate 71 has a smoke stack support 73 for holding a smoke stack 74 in the center, and the top plate 71 has a front inclined furnace wall 75 made of one or a plurality of wire mesh members and a rotating part 76. The point is that they are rotatably connected in series. Since the incinerator of the fifth embodiment is configured as described above, it is possible to reflect the flame by the top plate portion 71 and raise the temperature inside by radiant heat.
Further, since the smoke cylinder 74 is provided, the combustion efficiency can be remarkably improved due to the strong draft effect in combination with the wire mesh of the surrounding ventilation furnace wall.
